Molecular Structure
FAQ
How much is in each vial?
Each vial contains precisely the amount indicated on the label. For instance, a 10mg vial includes precisely 10mg of lyophilized peptide. Researchers may divide it into smaller fractions, such as four 2.5mg portions, while the total amount remains 10mg.
Does it come with instructions?
USA Peptides Direct products are designated for in vitro research. Prior to working with them, conduct thorough research. Our team will offer general assistance via text post-purchase.
What other supplies are needed?
Peptides come as lyophilized powder. They are not reconstituted, and any necessary bacteriostatic water or syringes must be obtained separately for research purposes.
How long does a vial last?
Peptides remain stable for up to 2 years in lyophilized powder form. After reconstitution, refrigerate and expect stability for about 2 months.
Is this intended for human or veterinary use?
No. This product is sold strictly as RUO and must not be used in humans or animals.
How should I reconstitute it?
Use sterile water or a compatible buffer; gently invert until fully dissolved. If your protocol requires sterility, pass through a 0.22 µm filter and aliquot to avoid repeat freeze–thaw.
Which in-vitro assays is PT-141 commonly used in?
Typical RUO uses include melanocortin receptor cAMP assays, β-arrestin/internalization workflows, radioligand binding, and LC–MS/MS method development.

Quality, Storage & Handling
Each lot is confirmed by HPLC (purity) and MS (identity); QR on the vial links to the batch COA. Independent U.S. labs verify purity, quantity, and endotoxin.
- Storage (lyophilized): −20 °C long-term or 2–8 °C short-term; keep desiccated and protected from light.
- After reconstitution: Use neutral, oxygen-poor buffer when possible; aliquot and store at ≤−20 °C; avoid repeated freeze–thaw.
- Working solutions: Prepare fresh; minimize exposure to light/alkaline pH to reduce degradation.
Shipping
Ships in validated cold-chain packaging. In-stock orders placed before the daily cutoff dispatch the same day. 2-Day FedEx/UPS is standard, with overnight options available. Automated text/email updates included.
